critical data you need—now!
WeatherLink for
Emergency
Response Teams
with Streaming Data
Logger
For use with the free
CAMEO® (Computer-
Aided Management of Emergency Operations) software developed
by NOAA and the EPA. With Vantage Pro2 or Weather Envoy,
provides the real-time weather data needed to map the footprint
of a hazardous plume, predict its dispersion, and help make critical
public safety decisions—all at just a fraction of the cost of other sys-
tems. For more about CAMEO, visit www.epa.gov/ceppo/cameo.
6550 WeatherLink for Emergency Response Teams $295
WeatherLink for APRS
with Streaming Data Logger
For ham radio operators, includ-
ing storm chasers and volunteer
weather watchers. Connects
a Vantage Pro2 console or
Weather Envoy to a ham radio
with TNC modem for instant
transmission of both your loca-
tion and the local weather con-
ditions via APRS.
6540 WeatherLink for APRS $195
With his chase vehicle outfitted with a Vantage Pro2,

WeatherLink for
Alarm Output
with Connector Block
Now you can turn heaters, fans, and other devices on or off using your weath-
er station. Software walks you quickly and easily through the choices—yet
the possibilities are almost unlimited! For each of four outputs, you can enter
up to eight different weather parameters. Enter threshold values for each,
select from nine different test conditions, and link the entries together as you
choose. For example, you could activate a fan to cool your house—but only if
the difference between the inside and outside temperatures is more than 5°F,
it’s more than 72°F inside, and it’s between 5:00 p.m. and 6:00 a.m. Our con-
nector block provides the interface between your
weather station and an electrical device. For
high-power devices, you may also need to add
electrical relays (not supplied by Davis).
6544 WeatherLink for Alarm Output $295
WeatherLink for
Irrigation Control
with Connector Block
Use your weather station to turn your irrigation system on or off. Connector
block connects directly to most irrigation systems including Rain Bird, Rain
Master, and Toro. For industrial controllers, provides electronic pulses for
wind, rain, and ET. For homeowners, looks at rain and ET values to determine
when to inhibit watering. Can also set console alarms to inhibit watering when
temperatures are too low or winds are too high. ET monitoring requires solar
radiation sensor. Connection to a PC is not required except for initial setup.
6560 WeatherLink for Irrigation Control $295
Agricultural/Turf Management
Software Module
Optional software module adds specialized reports
for farmers, growers, and turf managers, with user-
defined growing season and 24-hour period. You'll
get evapotranspiration, chilling requirement, leaf
wetness hours, and soil temperature hours—all with
user-entered thresholds and starting and ending
dates. Plus growing degree-days and temperature-
humidity hours (with user-entered names of crops,
pests, or diseases) and crop water management (with
irrigation values and user-entered K-factor profiles).
6511 Agricultural/Turf Management Module $95
For use with all WeatherLink models except Mac versions. Some reports
require the use of optional sensors. For owners of GroWeather who wish
to upgrade to Vantage Pro2, includes the ability to import files from
GroWeatherLink.
E-Mail/Phone Alert
Software Module
Be alerted whenever conditions
approach critical—24 hours a
day, 7 days a week. Choose e-
mail for detailed information on
alarm conditions plus regularly
scheduled updates on current
weather conditions. Or choose
the phone alert, with a special
alarm tone telling you to check
your weather station console or
WeatherLink for details.
6512 E-Mail/Phone Alert Module $35
For use with all WeatherLink models except Mac
versions. Because systems vary, the phone alert
may not work outside the USA.
Plug-in modules expand WeatherLink’s capabilities.
Data from the Vantage Pro station at the Ransom Road Grain Plant in Breckenridge, Michigan
is used by farmers for spray record keeping and pest management. Each year, the plant handles
enough grain to fill a train 78 miles long.
